| Popis: | In this paper the problem of a finite crack in a slab of functionally graded piezoelectric material (FGPM) is studied. It is assumed that the elastic stiffness, piezoelectric, and dielectric constants of the FGPM vary continuously along the thickness of the slab, and that the slab is under in-plane mechanical and electric loadings. Integral transform technique is used to reduce the problem to the solution of a singular integral equation. The stress intensity factor and the energy density factor are presented for various values of dimensionless parameters representing the crack size, the material nonhomogeneity and the magnitude of the electric loading. |
